Hey there, SGMD1, = )
I just wanted to say thanks for these super useful ups and for including the great instructions as well. Within just 3 hours of picking up my Droid 4, I used Dan Rosenberg's Motofail to root. At the time, I was so excited about it that I failed to consider how I would undo it in the event I needed warranty service which is now the case. Thanks again!
peace, = )
